AUTOMATIC FILLING-REPLENISHIING LOOM;

Application filed February, 16,1923. Serial No. 619,498.

1 '0 all whom it may concern Be it known that I, ALoNzo E. Becomes,

a citizen of the United States, and resident of Hopedale, county ofWorcester, State of Massachusetts, have invented an Improve successivelydischarged from the magazine into the running shuttle frombein'g carriedinto the shed.

The object of the invention is more particularly to provide means fortaking care of such filling ends when these ends are secured to theexterior of the hopper as, for example, in that type of constructionshown in the patent to Stimpson, 8%,945 granted November 6, 1906. y

A great deal of attention and inventive effort have been devoted to thecare of the filling ends left by the operation of automatic fillingreplenishment. While the greatest difficulty is experienced in the careof the filling end extending from the filling carrier discharged fromthe shuttle there is, nevertheless, a great deal of difficultyexperienced with the filling end'running from the fresh filling carrierto the point at which it is secured and held so as to enable the firstpick to be made properly; The present invention presents a simpleeffective and accurate means for insuring that this filling end shallnot be caught by the shuttle 'or the working filling and be carried orthrown into the shed. V

The nature and object of the invention will appear more fully'from theaccompanying description and drawings and will be particularly pointedout in the claims. The general nature of the construction and operationof the automatic filling replenishing loom being well known and familiarto those skilled in the art and those features thereof with which thepresent invention is particularly associated bein'g illustrated anddescribed in the aforesaid patent to Stimpson it is unnecessary here toillustrate and describe in detail anything more than those elements ofthe loom involved in a preferred embodiment of the present invention.

In the drawings: Fig. l is'an inner end view of'the hopper stand andhopper with a portion of the breast beam andlay shown in cross sec tron;

Fig. 2 is a view in front elevation of the hopper stand with the hoppershown chiefly in central vertical cross section; 1 Fig. 3 is a top planView of the main portion of the hopper stand.

' The breast'beaml of the loom is shown as supporting at'thereplenishing or right hand end the hopper which carries the supplyoffresh filling carriers. The hopper stand includes a base-2 bolted tothe breast beam and an upright or vertical flanged plate 3 which formsthe support 'for the rotary hopper and other working parts conor shaft 5upon which the hopper rotates.

The plate 3 slopes downwardly forwardly and rearwardly from this hub soas to leave exposed the main portion of the exterior eat of the hopperand enable the operator read- 11y to secure in placethefilling endsextending; from the filling carriers in the hopper. 1; its forwardportion the plate Sis provided with a hub 6 carrying the shaft or stud 7on which the usual transferrer 8 is mounted so that when the operationof filling replenishment takes place the transferrer 8 will swingdownwardly and its head 9 will carry the fresh filling carrier from thehopper down into the shuttle 10 on the lay 11 thereb'eneath and ejecttherefromthesubstantially exhausted filling carrier.

The hopper in the form illustratedcomprises the usualigenerallycirculardisks 12 and 13 secured to or forming part of the central sleeve 14journalled on the spindle 5.

1 At theinterior of the hopper and on the vide the minimum length offilling end extending from the securing means so that there will be aslittle waste of filling as possible. The filling end must be held when afresh filling carrier is discharged from the hopper so that the firstpick will be laid properly in and beaten into the shed and there mustaccordingly be some waste, but with this type of hopper the waste isminimized. In this type of construction a circular series of filling endholders is mounted on the exterior ofthe hopper as on the exteriorsurface of the disk 12. Preferably and for convenience this series ofend holders comprises one for each two filling carriers because twofilling ends may readily be connected to a single end holder. For thispurpose each filling end holder 20 is shown as a pair of spring pressedclamping disks between which the filling end is wound by the operator.These disks are supported on studs 21 secured inarms 22 projecting froma flange ring 23 secured to the exterior face of the hopper disk 12. Inthis convenient arrangement each filling end holder 20 is arranged on aradius extending between each adjacent pair of filling carrier seats 15.

One of the principal features of the invention resides in the provisionof separating positioning win'gs herein shown as rhoniboidal-shapedflanges 2 L projecting from the exterior of the hopper disk 12 and solocated as to insure thepeculiar and desired position of th'e runs offilling ends extend ing from the respective filling carriers to therespective filling end holders. These positioning wings or flanges areso located and arranged that each run of filllng extends from the hopperperiphery to its end holder in the direction of rotation of the hopperand forms a substantial angle with that radius of the hopper whichpasses through the point where the run of filling crosses the hopperperiphery. r

hen the filling carriers are placed in the hopper the filling 25 is ledby the operator around a pin 26, located for example on thecorresponding tip holder 19 and then back through a notch 26 in thehopper periphery in line with the seat in which the butt of the fillingcarrier'rests. This provides the necessary slack in. the filling toavoid breakage when transfer takesplace. The opera tor then carries thefilling end from the notch 26 down to and winds it about the proper endholder 20 thus securing it in place. The rhomboidal projecting flanges24: which constitute the separating and positioning wings in thisinvention are so located that the operator can only position the run offilling 25 extending from the notch 26 in the periphery to the endholder 20 in the desired manner. That is this run'of fill- 1ng mustbecause of the locatlon of the separating positioning wlngs extend inthe direction of rotation of the hopper and must he at a substantialangle with that radius of the hopper extending through the notchConsequently when transfer takes place and the fresh filling carrier isdischarged by the transferrer 8' into the shuttle the filling endextending therefrom is attached to a positioning device 20 which hasmoved well forward so that'when the filling end is cut, as by the usualtemple thread cutter, and left hanging it depends at a point Wellforward of the lay and in a position where it cannot be caught by theshuttle, the working filling or a moving part of the loom and be thrownor carried into the shed.

In order further to assist inthis position of the depending end afurther provision is made in the structure of the hopper stand.

The hopper stand isusually provided with a flange 27 projectingbeneaththe hopper forward of the position where the discharge of the freshfilling carrier from the hopper takes place. This flange 27 has rivetedor bolted thereto at 28 a plate 29 turnedupwa'rd at its rear end toconstitute a fixed abutment 30 against which the fill- 1ng carrier is guded as it is transferred into The invention, therefore, by the peculiararrangement and position of the separating and positioning flanges andby means of the slot in the flange of the hopperstand ensures that thefilling ends leftdepending from the filling end h olders'after transferhas taken place. shall move to a position 'where they cannot be caughtor thrown into the shed and form an imperfection in'the cloth. i

. Havingthus described the. invention what is claimed as new and desiredto be secured by Letters Patent, is:

1. An automatic filling replenishing loom comprising ahopper stand ahopper rotarily 'mountedin the stand, acircular series of seats at theinterior of the hopper to receive and support the-fresh fillingcarriers, a circular series of filling end holders on the exterior ofthe hopper, and separating positioning wings projecting from the hopperexterior, between the periphery and the cir- I i cular series of endholders, and located to ensure that each run of filling from the hopperperiphery to its end holder shallextend in the direction of rotation ofthe hopper and shall form a substantial angle with that radius of thehopper passing through the point where the run of filling crosses thehopper periphery whereby the filling end extending from the end holderafter transfer of the corresponding filling carrier will be carried wellforwardly out of the way.

2. In an automatic replenishing loom the a construction defined in claim1, together with a flange projecting from the hopper stand beneath thehopper forward of the point of discharge/of the filling carriers,

and presenting an elongated slot extending forwardly from its rear edgeand in the path of a filling end hanging from the end holder on thehopper to permit the said hanging end to move well forwardly out of theway after transfer takes place.

In testimony whereof, I have signed my name to this specification.
